Summary seminar Simon N’cho 18 May 2012

On Friday 18th of May 2012, Simon N’cho presented the progress of his PhD research during the AfricaRice PhD student seminar, organised at AfricaRice in Cotonou, Benin.

The seminar started at 10:35 and ended at 12:05. The seminar was attended by AfricaRice Program 3 scientists in addition to some agronomists and pathologists from other programs and chaired by Dr Diagne, the AfricaRice program 3 Leader.

After a brief introduction, Simon presented the Parasite project with an emphasis on the linkage between the four subprojects. After that, he has presented his own PhD project. This was followed by the methodology used for his project implementation and some preliminary results that stress perceptions of rice farmers of Rhamphicarpa threats. He ended his presentation with an outlook on the way forward.

This presentation was followed by a discussion session where 33 questions and comments from 10 of the participants were collected. These were mainly about the request for methodological clarification (sites selection, sampling approach and field data collection), analytical framework (DEA method versus Stochastic frontier approach, Double hurdle versus Heckman model, impact assessment parameter to be estimate), concept definition (infestation, infection, incidence, production systems ), potential factor affecting Rhamphicarpa infestation and damages (soil fertility status, farmer practices, plots historic, environmental factors), clarification about the linkages between the 4 sub-projects.

Dr Diagne commented that the use of farmer memory recall to estimate the evolution of Rhamphicarpa threats can lead to overestimation or underestimation that can pose risks related to the statistics due to possible memory loss of rice farmers as we go further back (5 years). This valuable comment will be consider to improve the final results.

At the end of the workshop, Simon stressed that the focus in the next period will be on descriptive and econometrics analysis of data collected in Benin and paper writing. He also presented his work agenda for complementary field work in Benin and baseline data collection in Cote d’Ivoire that should start by September 2012.
